From: Sergei Antonov <saproj@gmail.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 97a62eaefdc196969e9d3857f65fc8a90ee1fe3c upstream.
hfsplus_readdir() incorrectly returned DT_REG for symbolic links and special files. Return DT_REG, DT_LNK, DT_FIFO, DT_CHR, DT_BLK, DT_SOCK, or DT_UNKNOWN according to mode field in catalog record. Programs relying on information from readdir will now work correctly with HFS+.
